"She's now with Carrie and we're all heartbroken," Fisher said from Cedars-Sinai Medical Center, where his mother was taken by ambulance earlier Wednesday.

Reynolds’ death comes one day after the death of her daughter, Carrie Fisher. Fisher died on Tuesday, four days after suffering a heart attack on a flight from London to Los Angeles.

Fisher said the stress of his sister's death "was too much" for Reynolds.

Reynolds posted a heartbreaking message on her Facebook page Tuesday, thanking fans for their support after Carrie’s death.

One of the last remaining actors from Hollywood’s Golden Age, Reynolds first came to prominence when she landed the role of Kathy Selden in the 1952 classic “Singin in the Rain.” A string of successful movies followed, including 1964’s ‘The Unsinkable Molly Brown,’ for which she was nominated for a Best Actress Oscar.

The actress continued to find work later in her career, with roles as Aggie Cromwell in the Disney Channel’s ‘Halloweentown,’ movie series. Reynolds also had a recurring role on the sitcom ‘Will & Grace.’ Her portrayal of Bobbi Adler on the series earned Reynolds an Emmy nomination for guest actress in a comedy series in 2000.

Reynolds’ 1955 marriage to singer Eddie Fisher made the couple a popular target for tabloid headlines. The marriage ended in scandal in 1959, when Fisher left Reynolds to marry her best friend, fellow actress Elizabeth Taylor.

Reynolds would marry two more times, first to businessman Harry Karl from 1960 until 1973, and then to real estate developer Richard Hamlett from 1984 to 1996.

Debbie Reynolds is survived by her son, Todd and granddaughter Billie Lourd.
